The race speed calculator is the main function of the application. It's a versatile tool for runners that instantly updates distance, speed or time, as needed. Enter a race distance and a target time to check the required pace. Convert between pace per kilometer, pace per kilometer, or 400m. Standard race distances are available for selection or enter your own distance.

The cadence calculator tells you the length of your stride at a given pace. You can update the stride length or pace to see how the other is affected. For example, if I run a 5 km in 20 minutes at 180 steps per minute, how many meters I cover each stride.
